Citations not being formatted the same way in Word as in Endnote

I am using the Chemistry output style.

If I have a book then the preview pane in Endnote shows the reference as

 A. Earnshaw and N. N. Greenward, Chemistry of the Elements, Butterworth-Heinmann, 1997 , p. 210.

in word however this reference is shown as 

Earnshaw, A. and N.N. Greenward, Chemistry of the Elements. 1997: Butterworth-Heinmann. 210.

which is not the correct format for my references.

The same thing happens when I use a journal reference. 

In Endnote the preview pane shows my reference as

T. C. Dinadayalane, U. D. Priyakumar and G. N. Sastry, Journal of Physical Chemistry A 2004 , 108, 11433-11448.

In Word, the reference looks like:

Dinadayalane, T.C., U.D. Priyakumar, and G.N. Sastry, Exploration of C6H6 potential energy surface: A computational effort to unravel the relative stabilities and synthetic feasibility of new benzene isomers. Journal of Physical Chemistry A, 2004. 108 (51): p. 11433-11448.

The way that the references are being displayed in Endnote is correct, so why is it exporting them to word with a different format?

Many thanks

Thank you very much
